Assuming her boyfriend has access to the Internet, books and civilization, he can learn about diabetes himself. If he can't be arsed to even do a 0.3s google search about a debilitating disease his loved one is suffering from then why should OP even bother doing all that?

It depends how long they have been dating. I she really loves or likes him, she will take her time. If not, then no biggie, and move on.

Wow sounds like a jerk. Forgive him once but not twice

For the love of God... Has he been living in a cave?

If he's that selfish lazy and stupid, maybe he's not worth your time. He can't google it? Before he decided not to talk to someone, or to think it'll infect him, why didn't he look it up? That's a big step (breaking up/no longer talking to someone) to take without first verifying the facts...sigh

Diabetes isn't a laughing matter it's a legitimate condition

Shit. Is it fucked up that I thought that was hilarious?

They should allow people to type in italics for emphasis, cleaner and no need for "get it"s

You're*...

Diabetes ass!

Or as I say in the ER, type A for asshole..

Sounds like she's too sweet for him.

I second that motion!

I suppose he's on the shallow end of the gene pool...

Amen to that! Hehe (:

They've always been ignorant, if not more than today. Anyways OP, I hope you figure this thing out with him or look to your family for support. :)
